All gravy, no dry spots

An elaboration of the term “all gravy.” When something is not just good, but lacks any of the downside or dissatisfaction one may normally expect to encounter in an otherwise positive experience. It is a reference to the use of gravy as a sauce to cover drier foods, and refers to an evenly spread amount of gravy so that while eating the meal one does not find any dry spots where there is no or insufficient gravy.

Can also refer to sex that is good from start to finish.

That trip to the beach was all gravy, no dry spots! So glad the clouds didn’t show up till after we left.
